Hi, Welcome to Health Care Magic.
Fever,
weight loss,
fatigue and raised ESR shows you have an infection for which your body is showing defence (inflammatory reaction). Please don't be worried as i would exclude other common things before i go for TB.
For my patient, I would like to dig out some more history as
-FEVER when it started? is it continuous or increase or decrease?
-Do you feel tired all the time?
-Have you got cough? if yes, is it associated with sputum?
-Have you got any feeling of burning while peeing (micturation)?
-Is there any
abdominal pain or change in bowel habbits recently (loose motions)?
Please do the following tests as it would help to zero out on diagnosis
-
Complete Blood Count (CBC
-LFT's, RFT's, Serum electrolytes
-Chest x-ray if history of cough or Shortness of breath
-Urine routine examination
-Most important is perform a "Blood and Urine Culture and Sensitivity Test"
HOPE I HAVE ANSWERED YOUR QUESTION. PLEASE FEEL FREE TO CONTACT IF YOU STILL HAVE QUERIES. PLEASE RATE THE ANSWER AS YOU LEAVE.
WISH YOU BEST OF HEALTH!
